Technical Field

[0001] This utility model belongs to the field of fluoride-containing wastewater treatment technology, specifically a dosing device for fluoride-containing wastewater treatment. Background Technology

[0002] Fluoride wastewater treatment dosing devices are specialized environmental protection equipment that add chemical agents to convert fluoride ions in wastewater into precipitates or complexes to reduce fluoride levels. They are mainly used in the industrial sector dealing with fluoride wastewater, with the core objective of ensuring that the fluoride content in the wastewater meets the standards.

[0003] In existing technologies, fluoride-containing wastewater treatment dosing devices typically consist of a mixing tank, a dosing pipe, and a stirring assembly. After the operator discharges the fluoride-containing wastewater into the mixing tank, they add chemical agents into the tank and start the stirring assembly to treat the wastewater.

[0004] Existing dosing devices for treating fluoride-containing wastewater often result in the reagent floating on the surface of the wastewater during top-level dosing. Stirring alone is insufficient to quickly diffuse the reagent into the main body of the wastewater, leading to localized excessively high or insufficient reagent concentrations. Therefore, a new dosing device for treating fluoride-containing wastewater is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a dosing device for treating fluoride-containing wastewater.

[0009] Preferably, a magnetic plate one is fixed to the inner wall of the mixing rod; a magnetic plate two is fixed to the side wall of the cleaning scraper; both magnetic plate one and magnetic plate two are arranged inside multiple sets of spring columns.

[0010] Preferably, the mixing plate has mixing grooves on its sidewall; multiple sets of mixing grooves are provided on the sidewall of the mixing plate.

[0011] Preferably, the top of the multiple sets of mixing rods is fixed with a connecting ring; the outer wall of the connecting ring is in contact with the inner wall of the mixing box.

The whole device can achieve the effect of rapid diffusion of chemical agents from the bottom of the wastewater, effectively avoiding the problem of agents floating on the surface and having difficulty penetrating when adding chemicals from the top, improving the mixing effect of fluoride-containing wastewater treatment, and reducing the occurrence of local excessively high or insufficient agent concentrations.

[0020] Furthermore, such as Figure 3-4As shown, a connecting wheel 2 is rotatably connected to the bottom inner side of the mixing tank 1; the connecting wheel 2 is connected to the outer wall of the bottom end of the stirring rod 13; a connecting disc 21 is rotatably connected to the bottom inner side of the mixing tank 1; the connecting wheel 2 and the connecting disc 21 are connected to each other; multiple sets of mixing plates 22 are fixedly attached to the top of the connecting disc 21; during operation, as the stirring rod 13 rotates, it will directly drive the connecting disc 21 and the mixing plates 22 to rotate together through the connecting wheel 2, which can realize the direct mixing operation of the fluoride-containing wastewater at the bottom inner side of the mixing tank 1, effectively improving the uniformity of the mixing of fluoride-containing wastewater and chemical agents.

[0021] Furthermore, such as Figure 2-3 As shown, each of the multiple mixing plates 22 has a mixing rod 3 fixedly connected to its top; a cleaning scraper 31 is slidably connected to the inner side of the mixing rod 3; multiple sets of spring columns 32 are fixedly connected to the inner wall of the mixing rod 3; the cleaning scraper 31 and the spring columns 32 are interconnected; during operation, the end of the cleaning scraper 31 is made of elastic material, and the multiple sets of spring columns 32 can push the cleaning scraper 31 to move inside the mixing rod 3, so that the cleaning scraper 31 is in close contact with the inner wall of the mixing box 1. During the rotation of the mixing plate 22, the cleaning scraper 31 will be driven to rotate synchronously. The mixing rod 3 and the cleaning scraper 31 cooperate with each other to scrape off the substances adhering to the inner surface of the mixing box 1, thereby improving the cleanliness of the surface of the mixing box 1.

[0024] Furthermore, such as Figure 2 As shown, a connecting ring 6 is fixedly connected to the top of the multiple sets of mixing rods 3; the outer wall of the connecting ring 6 is in contact with the inner wall of the mixing box 1; during operation, the connecting ring 6 can support the multiple sets of mixing rods 3, making the mixing rods 3 more stable during long-term operation, thereby improving the service life of the mixing rods 3.

[0025] Furthermore, such as Figure 2As shown, a protective soft cylinder 7 is fixed to the outer wall of the mixing box 1; during operation, the protective soft cylinder 7 can block external objects, effectively reducing the occurrence of serious damage caused by direct collision between objects and the surface of the mixing box 1.

[0026] Working principle: During operation, the operator can add fluoride-containing wastewater into the mixing tank 1 through the inlet pipe 11, and then start the drive motor 12. The drive motor 12 will drive the stirring rod 13 to directly stir the fluoride-containing wastewater. When it is necessary to add chemical agents to the bottom of the fluoride-containing wastewater, the agent can be filled into the dosing cylinder 14. Then, the connecting plate 15 is rotated, and the push plate 16 is driven downward through the threaded rod 17. During the downward movement of the push plate 16, the chemical agent inside the dosing cylinder 14 can be directly transported to the bottom of the discharge tank 18 through the stirring rod 13.

The end of the cleaning scraper 31 is made of elastic material, and multiple sets of spring columns 32 can push the cleaning scraper 31 to move inside the mixing rod 3, so that the cleaning scraper 31 is in close contact with the inner wall of the mixing tank 1. During the rotation of the mixing plate 22, the cleaning scraper 31 is driven to rotate synchronously. The mixing rod 3 and the cleaning scraper 31 work together to scrape off the substances adhering to the inner surface of the mixing box 1, thereby improving the cleanliness of the surface of the mixing box 1. The magnetic plates 41 and 41 repel each other due to magnetic force, making the end of the cleaning scraper 31 fit more tightly with the inner surface of the mixing box 1. The overall device improves the cleaning effect of the cleaning scraper 31 on the adhering substances on the inner surface of the mixing box 1. Multiple mixing tanks 5 can assist the mixing plate 22 in mixing the fluoride-containing wastewater at the bottom of the inner side of the mixing box 1, further improving the mixing effect of the fluoride-containing wastewater and chemical agents. The connecting ring 6 can support the multiple mixing rods 3, making the mixing rods 3 more stable during long-term operation, thereby improving the service life of the mixing rods 3.
